- 1 claim. --.(c1.2-9912139) This invention relates to a nozzle to be used for tire hose, garden hose, or similar means for conveying and delivering liquids.

The primary object of my present invention is to generally improve the known nozzles of the indicated types.

Another important object of this invention is to provide an adjustable nozzle. My invention aims at a nozzle which can easily and reliably be regulated to deliver, for instance, water in form of a solid stream as well as in form of a spray. Further, it is intended to provide adjusting means which will make it possible to vary the amount of liquid discharged, in whatever way the discharge may take place, that is, as a solid stream or as spray.

Still another object of the invention is to provide adjusting means of the aforementioned kind, which will be simple and sturdy in construction and dependable in operation.

To the accomplishment of the foregoing and other objects which will appear hereinafter, my invention consists in the parts of the nozzle and the relation of the parts one to the other, as are described in the specification in detail and sought to be defined in the claim.

The specication is accompanied by a drawing in which:

Fig. l is a partially sectioned view of a nozzle embodying features of the invention, two relatively movable and detachable parts of the nozzle being shown partly detached; t

Fig. 2 is an end view in the direction of the arrow A indicated in Fig. 1;

Fig. 3 is a section taken in the plane of the line 3--3 of Fig.'2, with the left part of the two relatively movable parts of Fig. 1 omitted;

Fig. 4 is a view in the direction of the arrow B indicated in Fig. 1, with the same left part again being omitted;

Fig. 5 is a section taken in the plane of the line 5--5 of Fig. 4; and

Figs. 6 to 9 are explanatory of the operation of the nozzle, illustrating different operating conditions.

Referring to the drawing, a nozzle generally designated 10 includes a pipe 12 and a cup-shaped vessel 14, the pipe 12 and vessel 14 being integrally formed with one another. The pipe has an internally threaded end portion 16 to be threadedly connected, for instance, with a hose fitting, and tapers gradually toward its discharge end. The bore 18 of the pipe opens at the passage 20 into the cup 14. The cylindrical wall 22 of the cup is exteriorly threaded to receive the matngly threaded cylindrical wall of a cap 24. The cap is likewise cup-shaped and encloses to gether with the cup 14 an enlarged chamber 26. The tlat outer wall 28 of the cap 24 has two identically sized discharge openings 30 and 30a (see, for instance, Fig. 2), which are provided equidistantly from, and along a straight line through, the center of the wall 28.

Rotatably arranged within the chamber 26 and in contact with the wall 28 is a valve disc 32 provided with two differently sized apertures 34 and 36 (best seen in Fig. 4).

The pin 42 is supported in the wall 28. The valve disc may easily be revolved by turning the arm 44 either clockwise or counterclockwise.

As can clearly be seen from Figs. 2 and 6 to 9, the wall 28 is provided on its outer surface, in a circular and spaced arrangement, with four depressions I, II, III, and IV (see also Fig. 5). The arm 44 which is made, and secured to the pin 42, to be resiliently urged toward the wall 28 carries a projection or lug 46 tending to snap into one of the depressions. t

When the cap 24 is tightly screwed onto the cup 14, the discharge opening 30 is in alignment with the passage 20. The valve disc 32 can be revolved so that either one of the apertures 34, 36 will be in line with both the passage 20 and one of the discharge openings, that is, either 30 or 30a.

In operation, when the passage 20, the aperture 34, and the discharge opening 30 are in alignment, this condition being indicated in Figs. l to 6, a solid stream of water, when the nozzle is used with a fire hose, will be delivered. In this position, the aperture 34 and the discharge opening 30 register, whereas the aperture 36 is closed by the wall 28, and the discharge opening 30a is closed by the valve disc.

With right-hand threads used on the cup 14 and the cap 24, it is advisable to turn the arm 44 to the right, in case a condition other than that of Figs. l to 6 is to be established.

The arm 44 is pressed slightly away from the wall 28 to unlock the arm. With the lug 46 released, the arm is turned into the position shown in Fig. 7, in which position the discharge opening 30 is closed, and the aperture 36 and the discharge opening 30a are aligned. The water surging into the eccentrically arranged chamber 26 will be disturbed by the cylindrical wall 40 so as to be discharged through the small aperture 36 in form of a narrow spray.

Upon further revolving the valve disc, the position shown in Fig. 8 is reached. In this position, the discharge opening 30 is closed, and the discharge opening 30a is in register with the larger aperture 34. The water is now discharged in a form of a wide spray.

In the position shown in Fig. 9, the discharge opening 30a is closed, and the discharge opening 30 is in register with the small aperture 36, which condition ensures the delivery of a narrow solid stream of water.

It is believed that the construction and operation of a form of nozzle for practicing the invention, and the many advantages thereof, will be fully understood from the foregoing detailed description. lt will be clear that the invention makes it possible, by simply revolving the valve disc by any suitable means, to arrange for the delivery, for instance, of water in form of a solid stream or in form of a spray, wider and narrower in each case. The charnfers 37 and 38 serve as guides for the discharge.

It will be apparent that while I have shown and described my invention in a single form only, many changes the spirit of the invention defined in the following claim.

I claim:
